I’m also not talking about the phone alone, but “listening” across all your devices. There’s a identifying connectivity there, and one that I’ve never consented to.
I know a couple guys who are highly placed in the spooky world. 3-letter agency stuff. I know it’s probably not necessary, but I never mention their names in reference to their jobs. Never know what is listening.
I disable any camera or microphone I don’t want, and don’t use smart devices. I’m a “one motor, one machine” sort of guy.
